Operations that can be performed using Custom Code

Problem Statement

This article describes what you can do with Chargebee’s Custom Code feature, including subscription changes and restricting addons by plan.

Related Scenarios

  • What actions can be performed using custom code?
  • How to restrict specific addons on selected plans?

Solution

Custom Code is a Chargebee feature that lets you run logic that is not available through the API alone. Examples:

  • Subscription changes: Control whether a subscription change is applied immediately or at the end of the term using fetchChangeSubscriptionOptions.
  • Addon and plan configuration: Use fetchAllowedPlanConfig to:
    • Specify allowed addons
    • Specify allowed addons for a particular plan
    • Auto-attach addons to a plan when selected
    • Specify quantity meta for a plan or addon

Note

You cannot restrict addon downgrade or remove the quantity decrease ("-") button on the portal via this config.
